Texas Lu force hydraulic machinery plant (www.luliyeya.com) is specialized in "jacks, electric pumps, hand pumps, cylinders," the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Lu Jingli. Traditional electric pump control system in what is technically a lack of electric pumps are mechanical devices, are commonly used in the construction of the device. However, due to technical limitations, conventional electric pump control system has certain application defects. The following brief introduction by the inadequacies of small series under their control systems. We all know that the electric pump diaphragm metering pump control is part of the motor control, if only to control the use of traditional phenomenon of trapped oil pump speed, you need to install speed devices. But whether it is installed magnetoresistive magnetic sensor or electric pump electric pump core tachometer, or Hall sensors and other types of sensors, the motor will increase the volume, higher costs, besides any error will cause the electrical sensor armature current increases and the motor efficiency is reduced, causing increased electric fuel pump core two-way electric heat pump, and motor manufacturing process requirements increase and other issues. Electric pump properly install them around the sealing means sealing means belonging to important parts of the electric pump, although not a major component, but also indispensable. Only properly installed around the sealing device, in order to ensure the normal operation of the electric pump, extending its life. Install an electric pump seal around need to follow the operating specifications, can not just well, and different sealing device mounting points are different, now mainly small series to introduce you to one of the more important of the four considerations: 1 The electric pump O-ring during installation, do not pull the permanent deformation of the extent of its electric pump action, and do not suit the side scrolling side edge, or it may be due to the formation of distorted shape and oil spills. 2. The electric pump seal sliding surface as fit assembly should be coated with an appropriate amount of hydraulic oil. 3. Install Y-shaped and V-shaped ring, pay attention to the direction of its installed electric pump installed instead to avoid spills. Y-shaped ring, its lips addition, Yx-ring is also a distinction shaft or hole, do not install the wrong. When the V-ring and dust ring by ring seals should all electric pump plunger seal ring, bearing ring seal ring can create an opening for the state to install the seal ring should be shaped different support ring, pressure oil chamber; When the electric pump to adjust the pressure ring, should be limited to not leak, not too tight, to prevent the seal resistance is too large. 4. Remove the O-ring after renewal.
